Zodiac – Magna Hydrox mid electrode – R0636301

The Zodiac Magna Hydrox Mid electrode (R0636301) is a genuine replacement mid-grade electrode cell designed for use with Zodiac’s MagnaPool Hydroxinator salt chlorination systems. This electrode is the core electrolytic component responsible for converting dissolved magnesium and potassium mineral salts into free chlorine, keeping your pool water sanitised, clear, and comfortable without the need to handle harsh chemical products manually. As a direct OEM replacement part, it ensures your Hydroxinator system continues to operate at its designed efficiency and output level.

The electrode measures approximately 77 mm in diameter and is engineered to fit precisely within compatible Hydroxinator cell housings. Genuine Zodiac electrodes use coated titanium plates, which provide durability and resistance to the demanding electrochemical environment inside a salt chlorinator cell. The reverse polarity function built into compatible Hydroxinator iQ systems helps to self-clean the electrode surface during operation, reducing scale build-up and extending service life.

Technical characteristics and compatibility

The R0636301 Magna Hydrox Mid electrode is designed to be compatible with the following Zodiac MagnaPool systems:

• MagnaPool Hydroxinator
• Hydroxinator iQ
• Hydroxinator iQ pH
• Hydroxinator iQ PRO

The “mid” designation refers to the output capacity tier of this electrode within the Hydroxinator product family, making it suited to mid-range pool volumes. The electrode is approximately 77 mm in diameter, and its construction follows Zodiac’s OEM standards to ensure correct electrical contact, flow characteristics, and chlorine output when installed in a compatible cell body. Using a genuine Zodiac replacement electrode preserves the integration between the cell and the Hydroxinator control unit, maintaining accurate readings and automated dosing behaviour.

Suitability and buying guidance

This replacement electrode is intended for pool owners and technicians who need to restore the chlorine-generating performance of a Zodiac MagnaPool Hydroxinator system. Over time, electrode plates wear through normal electrolysis, and replacing the electrode is the standard maintenance procedure to restore full chlorine output. The R0636301 mid electrode is appropriate for mid-sized residential pools running any of the compatible Hydroxinator iQ variants listed above. If you are unsure whether this is the correct electrode tier for your system, consult your Hydroxinator model documentation or compare the part number against your existing cell label before purchasing. Always use genuine Zodiac replacement electrodes to maintain system warranty and performance standards.
